I am one hundred percent support this proposal.

Just to clarify, did you consider shunit2
<https://github.com/kward/shunit2/> [1 <https://github.com/kward/shunit2/>]
as a unittest framework for Bash? It seems a little bit closer to shell
scripting itself, so you don't need to learn another syntax to write

Best regards,
Oleg Gelbukh
